I'm up to page 10 of Dr Dick's thread. All Girls Garage on in a couple minutes. Gotta love those girls.

That post was illustrating radial clearance between fork radius and the radius where the fork rides in the gear. The thickness of the fork can introduce a small level of “slop” into the shift, but it’s not really enough to hurt anything unless the face of the fork that rides in the gear slot are severely worn too. Then you are looking at dogs being forced apart and/or missed shifts, and excessive forces applied to the finger rollers, etc... from not enough gear travel from too loose clearances.

I was still curious so I measured the side clearance between the fork blade and the slider gear groove. It was .008" for the m/s gear and .009" for the c/s gear.

I checked the sides of the fork blades and compared them with Dr Dick's pic. My blades do not have the wear triangle at the tip of the side of the blade, and the sides of the blade crescent show very little wear - I can't feel it with my fingernail.



So I'm going to go with these forks.

In bad news, my Eastern top hats measure .289" ID, .369" OD, and can be filed fairly easily. So I'm looking for NOS H-D top hats.

I did see that but I don't have a good grinder.

But I will see if anyone on eBay has NOS H-D 34168-39 top hats...
